Reconfigurable Telltale (RTT) Indicators

Auto Hold RTT Indicator 

The IPC provides the RTT indicator to inform the driver of the auto hold system status (on, off or unavailable). The IPC receives the auto hold indicator request from the GWM over the HS-CAN1. The GWM receives the auto hold indicator request from the ABS module over the HS-CAN2.

Auto Stop-Start RTT Indicator 

The auto stop-start RTT indicator informs the driver of the following states:

• solid green - the auto stop-start feature has temporarily turned off the engine.
• solid amber - a stop-start system concern exists.
• flash in either green or amber - system state as determined by the PCM.

The IPC receives the stop-start indicator request from the GWM over the HS-CAN1. The GWM receives the stop-start message request from the PCM over the HS-CAN3.

Blind Spot Monitoring System (BLIS®) Off RTT Indicator 

The IPC provides a RTT to inform the driver the Blind Spot Monitoring System (BLIS®) is turned off. The IPC receives the cross traffic alert left status and cross traffic alert right status messages from the SODL and SODR through the GWM over the HS-CAN3.

Charging System RTT and Message Displays Indicator 

The IPC provides a charging system RTT along with message displays indicating the status of the charging system. When a fault is present in the charging system, the BCM sends the battery low state of charge message to display message center warning messages and the charging system Reconfigurable Telltale (RTT) warning indicator.

The IPC receives the battery low state of charge message from the GWM over the HS-CAN3. The GWM receives the battery low state of charge message from the BCM over the HS-CAN1.

Cruise Control RTT Indicator 

The IPC uses the following messaged inputs to control the cruise control RTT:

• Cruise control status
• Cruise control set speed
• Cruise control override

The IPC receives the cruise control messages from the GWM over the HS-CAN3. The GWM receives the cruise control messages from the PCM over the HS-CAN1.

Door Ajar Indication Reconfigurable Telltale (RTT) Warning Indicator and Message Displays 

The IPC provides a door ajar Reconfigurable Telltale (RTT) warning indicator along with message displays to indicate the status of the doors or liftgate. The BCM monitors each of the ajar inputs and sends a door ajar status message to the GWM over the HS-CAN3. The IPC receives the door ajar status message from the GWM over the HS-CAN1 to display the specific ajar Reconfigurable Telltale (RTT) warning indicator and corresponding warning message.

Engine Over-Temperature Reconfigurable Telltale (RTT) Warning Indicator 

The IPC provides a Reconfigurable Telltale (RTT) warning indicator to alert the driver the engine is over temperature. The IPC receives the engine overheat indication request and the engine coolant temperature data from the GWM over the HS-CAN3. The GWM receives the engine over-temperature message from the PCM over the HS-CAN1.

Low Fuel Reconfigurable Telltale (RTT) Warning Indicator 

To supplement the fuel gauge indication, the IPC provides the low fuel Reconfigurable Telltale (RTT) warning indicator. When the fuel level reaches 1/16 of a tank and 80 km (50 miles) DTE for MyKey® users, the IPC illuminates the low fuel Reconfigurable Telltale (RTT) warning indicator.

Low Oil Pressure Reconfigurable Telltale (RTT) Warning Indicator 

The engine oil pressure switch is hardwired to the PCM. The PCM provides the engine oil pressure indicator request and engine RPM data to the GWM over the HS-CAN1. The IPC receives the oil pressure warning indicator request and engine RPM data from the GWM over the HS-CAN3. The IPC requires engine RPM above 400 RPM before the message center displays the low oil pressure RTT.

Low Washer Fluid Level RTT Indicator 

The low washer fluid level switch is hardwired to the IPC through a single signal circuit and is grounded through a separate ground circuit. The IPC provides a reference voltage to the washer fluid level switch. When the washer fluid is low, the washer fluid level switch closes to ground, pulling the reference voltage low. When the IPC detects the washer fluid input pulled low, the IPC illuminates the low washer fluid level Reconfigurable Telltale (RTT) warning indicator.

Powertrain Malfunction (Wrench) RTT Indicator 

The IPC provides a powertrain malfunction (wrench) RTT to indicate transmission, transmission range control Electronic Throttle Control (ETC), AWD and BCM concerns.

The IPC receives all the required messages from the GWM over the HS-CAN3.

The GWM receives the body service required message from the BCM over the HS-CAN1.

The GWM receives the GSM service required message from the GSM over the HS-CAN2.

The GWM receives the TRCM service required messages from the TRCM over the HS-CAN2.

The GWM receives the transmission service required, engine service required and the AWD service required messages from the PCM over the HS-CAN1.
